Hi, I've been having a problem with my new laptop. It was running fine for the first couple weeks I had it, but now about every 30 to 45 seconds or so, it has a short (maybe half a second) moment of unresponsiveness. I notice it most in Photoshop and other graphics programs where it'll miss a couple strokes while drawing or writing, which results in a straight non-pressure sensitive line between where the cursor was before the stall and where it is after; but the problem is not limited to any specific application. I notice it while typing sometimes too, where it's just long enough to miss a keystroke or two.
I can't tell if it's a hardware or software problem, and I don't know where to start on trying to diagnose it. I ran a full boot-time scan with Avast and a full scan with SpyBot S&D, and both came up clean. I defragged the HDD, but that had no effect. Chkdsk didn't find any damaged sectors either.
The problem started after a flight where the laptop was stored in my checked baggage, and it also suffered a couple short accidental falls onto a carpeted floor, so I'm inclined to think the problem might be hardware related. It's still covered under a warranty that's supposed to cover that, but it's currently my main computer, so I'm trying to avoid sending it out and having to go without it for however long it takes to be serviced and having to reinstall all my software and stuff if I can avoid it.
I know this is sort of a vague issue, but any help you can give me would be greatly appreciated.
The computer is an HP Pavilion dv7 with an Intel Core-i5 3210M CPU @ 2.5Ghz, 8GB RAM running Win 7 SP1.
